In a plasma membrane how do the tails of the phospholipid molecules lineup?
they are sandwiched between two layers of heads
What are the specialized parts of a phospholipid bilayer?
The Phospholipid Bilayer is made up of phospholipids. These phospholipids have a hydrophillic head, and a hydrophobic tail. They are structured so that the hydrophillic head interacts with water, and the hydrophobic tails stays away from water, but mixes with fat. This makes the phospholipids form the phospholipid bilayer. The Phospholipid Bilayer has intrinsic proteins and extrinsic proteins attached, which may have glycoproteins attached to them. Glycolipids may also be attached to the hydrophillic heads of the phospholipid. Cholestrol is also part of the phospholipid bilayer, which adds strengh to the structure.

Because of its chemical-structural composition the cell membrane is called?
phospholipid bilayer. I had a straight 100% average in my anatomy class so you can take my word for it.
What structure surrounds the cell and provides support?
In a plant cell, its the cell wall, an animal cell does not have a cell wall so its the cell membrane

Which part of a cell controls what gets in and out?
The plasma membrane / cell surface membrane. The phospholipid bilayer prevents certain substances passing straight through, so protein channels and other mechanisms control what does and does not pass in and out of the cell.
What do cell walls do in plant cells?
They keep the structure so that the contents of the cell do not spill out.

Why is a cell so important?
A cell is important because you could not live without them.
What organelles should not be in your animal cell?
The definition of organelles is that they are inside the cell; inside the cell membrane (phospholipid bilayer). So anything that is inside the cell, other than the organelles, are treated as invaders, and the lysosomes will attack and digest them. This is a part of the body's immune response
What type of hormone characteristically requires a second messenger?
First messengers may not physically cross the phospholipid bilayer cell membrane to initiate changes within the cell directly and so require a secondary messenger. Second messengers may be coupled downstream to multi-cyclic kinase cascades to greatly amplify the strength of the original first messenger signal.Calcium ions are one type of second messengers and are responsible for many important physiological functions including muscle contraction, fertilization and neurotransmitter release.cAMP is also a second messenger.First messengers may not physically cross the phospholipid bilayer cell membrane to initiate changes within the cell directly and so require a secondary messenger.
Each plant cell has Structure X Structure X makes a copy of itself before before the cell divides into two new cells What is Structure X?
structure X is the DNA or genetic material eg the chromosomes, which has to copy itself so that the new cell has information so that it can do basic funstions like respire. etc
Why are chloroplasts so important in a plant cell?
so that the cell can get the food and nutrients it needs
Why is the cell so important?
The cell is so important because it keeps you in touch with your friends and family. some people think their cell is their life. and you think why not use a telophone but you can also text on a cell.
